Also, the wall 'of the dovetail-shaped base53 interlocks beneath the undercut wall 51 of the depression in the rimbase, which thus positively holds the base of the retaining flange fromlifting out of its seat.

Figs. Sand show a modified form of rim embodying certain features of my.inven- .tion. In. the structure shown in these figures, the rimcomprises integral therewith, and having near the edge opposite tov the.flange (30 an inwardly projecting rib (31. The side wall (32 of this ribis preferably substantially vertical, while the bottom wall 63 thereoftapers outwardly toward the edge of the ring. The second part of the rimconsists of a transversely splita'ing-fil which con'iprises the inclinedportion (55 lying parallel'with the inclined surface 63 of the rib 61,and the tire-retaining flange (Ki. The inner edge of the portion 65 ofthe ring is turned up to form a flange (3T engaging the wall (32 of therib (S1. The ringjtis is preferably split diagonally as indicated M68 inFig. It will be seen that the stress put upon the flange T36 by theinflated tire will be transmitted substantially in the line of theinclined portion 65 of the split flange to the engaging surfaces oftherib '61 and flange (57. The disposition of the parts is thus the mostefficient obtainable for resisting the stresses caused by the inflatedtire. These stresses have no tendency to unhook the flange 67 from therib (31. tapered surface 63 at the side of the endless ring 59 alsoserves to facilitate theapplication of a split ring to the endless ringby guiding the flange (57 to its proper posil 1 I fe .b'lyi removablymounted upon the I \vliee'l.'; fo 1-example, as shown in Fig. 8. .Forthis purpose the felly 69 of the wheel, if of I wood, is provided with ametallic felly band I0 which has a flange 71 at one edge thereof. Thisflange is preferably bent to provide an inclined bearing surface :72adapt edfto engage the under-surface of the inclined part of the splitring (34. Thus, when the rim is mounted upon the felly band. the ring(ii is effectually heldin position b v its engagement with the flange of.theifelly band. The rim may be held upon the folly band in any suitablemanner; forexample, wedges 73 maybe inserted between the felly band andrim, the wedges being secured to the wheel by means of bolts 74 and nuts75.
